			==Circuit Order==
			Based on [[Paul Log]] - here is height controller, using the Capacitive to Digital Converter chip [[AD7747]]

			Hello Anthony/Marcin,

			Thank you for your order, please confirm you require our Plus Service for "Open Source ecology" as
			your data included solder masking and a top legend, however you requested our Basic Service which does
			not include these options.
			Your two PCB order with out Plus Service as shown in the attached image file is $21.96 US before
			shipping handling and taxes on a three business day turn. We require your confirmation of Service Type
			to proceed with manufacturing.

			Best Regards,
			Support

			We are holding your order until we will receive authorization to
			proceed or we receive your layout modifications.

			Please review the attached JPG(s) and advise us how to proceed.
			Red is Top layer, Blue is Bottom layer, and Green is Drill locations.
			Note: Bright White pad locations indicate plated hole locations.

			When regenerating new data please send a complete zip package containing:
			Gerber files, apertures if necessary, NC drill file, tool list, and an
			order form to support@apcircuits.com referencing your original order number.

			Should you have any additional questions, or require additional data,
			please contact us, at your earliest convenience.

			Thank you.

	Ramps 1.4 Heater circuit to be used for oxygen solenoid. Connector is a 6 terminal, screw terminal block. Solenoid voltage must be same as stepper voltage supplied to ramps board. Typically 12 or 24 volts DC. [[Image:180px-RAMPS1-3 6pos.JPG\|100px]]		Ramps 1.4 Heater circuit to be used for oxygen solenoid. Connector is a 6 terminal, screw terminal block. Solenoid voltage must be same as stepper voltage supplied to ramps board. Typically 12 or 24 volts DC. [[Image:180px-RAMPS1-3 6pos.JPG\|100px]]

	Stepper motors are 425 oz.in 4 volt 2.8 amp. This exceeds the 1-1.5A capability of the ramps Pololu drivers. Decision has been made to use the Powerlolu board at [https://github.com/fluidfred/powerlolu] Open source schematic seems ok(Eagle format). Board file seems unfinished. Powerlolu drive capability is 10A. [[Media:Powerlolu_web_preview_featured.jpg]] The board is commercially available at [https://shop.germanreprap.com/en/Powerlolu] This board does not directly attach to the Ramps board, but uses 4 wires to attach to one of the sockets that the Pololu board plugs into on the ramps board also commercially available. Note #1 - This is not very mechanically or electrically stable. Note #2 - The Powerlolu board is current limited but not fused. The power supply to the board should have an inline fuse no greater than 10A. To set the driver current limit see [http://www.germanreprap.com.au/en/support/documentation/Powerlolu]. Stepper motor connects to Powerlolu via two screw terminal blocks.		Stepper motors are 425 oz.in 4 volt 2.8 amp. This exceeds the 1-1.5A capability of the ramps Pololu drivers.

	Use a seperate Arduino Mega for the height control system. Requires a seperate Ramps & Powerlolu board for the z-axis stepper. Requires a custom software sketch in the Arduino to connect Ramps to the capacitive height sensor, or could be prototyped with the [http://www.digikey.com/product-search/en?mpart=EVAL-AD7747EBZ&vendor=505 $70 eval board]. Requires some pushbuttons for jog up/down and engage/disengage height feedback. With some custom g or m codes and a serial line between the two Arduinos the attached pc could jog the z-axis and engage/disengage feedback instead.

	This is confusing. Heat sinks are normally specified in terms of watts per degree C, not watts. 35 watts/degree C is a very large heat sink. If it is really this high, I would recommend water cooling.		This is confusing.
